Fintech Street
Platform

Trading infrastructure, working end to end.

Fintech Street is a private prototype by Realtime Software Inc. It shows how identity, embedded wallets, market data, order management and external trading providers come together in one product.

01

Wallets & identity

Privy authenticates the user and provisions a self-custodial embedded wallet. The server verifies every session token and maps the Privy identity to an internal account. Only public addresses are stored — never keys or recovery material. A wallet-provider abstraction lets Turnkey or another authorized provider slot in later.

  • Email and social login
  • Embedded EVM wallet
  • Server-verified sessions
  • Provider abstraction
02

Market data

Provider adapters translate each venue’s feed into one normalized instrument, quote, order book and candle model. Every value carries provenance — provider, mode and timestamp — so simulated or stale data can never pass as live. Perpetuals stream from Kraken Futures public data today.

  • Normalized instruments
  • Provenance on every price
  • Server-side caching
  • Explicit unavailable states
03

Trading engine

Orders are validated on the server, checked against collateral and risk limits, and processed idempotently. Fills update positions, margin and P&L under documented, deterministic rules. Every balance change is a double-entry journal that must net to zero, with an append-only audit trail.

  • Idempotent order submission
  • Margin & liquidation modeling
  • Double-entry ledger
  • Append-only audit log
04

For brokerages

Fintech Street demonstrates how Realtime Software can help a brokerage add trading to its own products: broker account mapping, funding workflows, order routing, position sync, pre-trade risk checks and integration health — each behind a capability-driven adapter contract.

  • Broker account adapters
  • Reusable trading UI
  • API-driven architecture
  • Integration diagnostics
How it works

From sign-in to settled position.

The full path a user takes — and exactly where identity, custody, collateral and execution responsibilities sit.

  1. Sign in with Privy

    Email or social login. The server verifies the session token and maps the identity to an internal account — browser-supplied user IDs are never trusted.

  2. Embedded wallet, provisioned

    A self-custodial wallet is created at sign-in. Fintech Street stores only the public address — never keys or recovery material.

  3. Simulated collateral, kept separate

    Your trading account receives explicitly simulated USD, recorded in a double-entry ledger that never mixes with on-chain wallet assets.

  4. Trade on live market data

    Orders are validated server-side, checked against collateral and risk limits, and filled idempotently against identified, timestamped prices.

  5. Positions, P&L and audit trail
